Loading the Wire Spool

Maximum 5kg spools. Accepts plastic, steel and fiber

spools onto 51mm spindle. It is possible to use other

spools after using the appropriate adapter, which can be

purchased separately (see "Accessories" chapter).

Loading the Electrode Wire

Turn the input power OFF.

Open the spool wire case.

Unscrew the locking nut of the sleeve [13].

Load the spool wire on the sleeve so that the spool

turns clockwise when the wire is feed into the wire

feeder.

Make sure that the spindle brake pin goes into the

fitting hole on the spool.

Screw in the locking nut of the sleeve.

Open the wire drive door.

Put on the wire roll with the correct groove

corresponding to the wire diameter.

Free the end of the wire and cut off the bent end

making sure it has no burr.

WARNING

Sharp end of the wire can hurt.

Rotate the wire spool clockwise and thread the end

of the wire into the wire feeder as far as the Euro

Socket.

Adjust force of pressure roll of the wire feeder

properly.

Adjustments of Brake Torque of Sleeve

To avoid spontaneous unrolling of the welding wire the

sleeve is fitted with a brake.

Adjustment is carried by rotation of its screw M10, which

is placed inside of the sleeve frame after unscrewing the

brake locking nut.

Figure 8

18. Locking Nut.

19. Adjusting Screw M10.

20. Pressing Spring.

Turning the M10 screw clockwise increases the spring

tension and increase the brake torque

Turning the M10 screw anticlockwise decreases the

spring tension and decrease the brake torque.

After finishing of adjustment, you should screw brake

locking nut again.

Adjusting Pressure Roll Force

The pressure arm controls the amount of force the drive

rolls exert on the wire. Pressure force is adjusted by

turning the adjustment nut clockwise to increase force,

counterclockwise to decrease force. Proper adjustment

of pressure arm gives the best welding performance.

WARNING

If the roll pressure is too weak, the roll will slide on the

wire. If the roll pressure is set too heavy the wire may be

deformed, which cause feeding problems in the welding.

The pressure force should be set properly. For this

purpose decrease the pressure force slowly until the

wire just begins to slide on the drive roll and then

increase the force slightly by turning of the adjustment

nut by one turn.
